The default High-Level WYSIWIG Email Editor doesn't have the ability to Left-Align the full body of the email.
If you want that functionality, please vote and comment on the Feature Request here.
In the meantime, if you want Left-Aligned emails, this approach works (and only takes a few extra minutes):
- Design your Email in one of the 3rd party WYSIWIG Email Editors that exist that create compliant HTML code (we personally love and use Stripo for this, however make sure you do your own due diligence before picking a vendor)
- When you start the email, choose the Code Editor instead of the Design Editor:
- Paste in the HTML from Stripe to the Code Editor
- Voila - you're good to go :-)
This approach only takes an extra few minutes and results in extremely compliant HTML code (making sure your email shows up perfectly across as many platforms / devices as possible).
Again, if you want the Design Editor to have this functionality, please vote and comment here.
